That rainbow was just a mistake- the photo was open in Photoshop and I somehow smeared the "pattern stamp" tool on it and that's what happened. It looked so weird I kept it, and added a shadow. But yes I thought of LOST also. Like Lost on Fire Island, or also wouldn't it be wild if this is secretly what rainbows looked like before they got touched by mist and sprung into the sky, like a straw-wrapper snake.
